C. P. STILLMAN. TRO-TTING SULKY.

Patented Feb. 9, 1886.,

UNITED STATES PATENT OFFICE.

CHARLES F. STILLMAN, OF NEWT YORK, N. Y.

SPECIFICATION forming part of Letters Patent No. 335,651, dated February9, 1886.

Application led May 17, 1833.

To all whom it may concern:

Beit known that I, CHARLES F. STTLLMAN, of the city, county, and Stateof New York, have invented a new and useful Improvement inTrotting-Sulkies, of which the following is a specification.

The invention relates to that form of sulky for which Letters Patent No.237,924, February 15,1881, and No. 244,404, July 19, 1881, have hithertobeen granted to me, and in which devices the drivers seat is arrangedover the back of the horse instead of in rear ofthe animal, as isordinarily the case. y

rI he present invention consists in improvements in mechanicalconstruction, whereby greater strength is secured,and liability toinjury from strain in large measure obviated.

ln the accompanying drawings, Figure l is a side elevation, and Fig. 2is a plan view, of my improved sulky, shown attached to the horse.

Similar letters of reference indicate like parts. y

A A are the wheels, which are journaled upon short horizontal arms ofthe axle,which passes up over the back of the horse. Said axle isdonbled-that is to say, it is formed of two portions, B and B, whichdiverge as they extend upward and are fastened to each end ot' theseat-frame I. This construction ot' the Renewed June 29, 1885.

Serial No. 170,150. (No model.)

axle I find of especial advantage in point of strength and indistributing the strain, so that the axle as a whole is not liable toinjury by the twisting effect due to the motion of the horse.

C C are the shafts, which do not meet. 0n the rear end of each shaft Iattach a cap or a collar, F, from which extend the braces D to theaxle-arms, and braces E tothe rear corners of the seat-frame I. Also,from collars, near the front portion of the shafts, extend braces G tothe axlearms,and braces Hto the front corners of the seat-frame I. Theseatframe has braces J extending across its interior, and curvedstrengthening-pieces K are arranged, as shown, lbetween the braces E Eand H H. 1

The structure thus formed of axle, shafts, and braces is one of greatstrength and rigidity, and is a material improvement over any form ofsulky of this class hitherto produced.

I claim as my invention- In a trotting-sulky, the combination of thedouble axle B B, shafts C, braces D, braces E, braces G, braces H, andseat-frame I, substanti-all y as described.
